Synthesis , characterization of some new heterocyclic compounds and evaluating their biological activity

Abstract

Abstract This work involves synthesis of some heterocyclic compounds including 2- amino-5-[(3,5-dimethyl phenoxymethylene)-1,3,4-thiadiazole [3]. 2-( substituted benzylidene)-1,3,4-Thiadiazole -5- (3,5-dimethyl phenoxy methylene [4,5]. 2- [ p-nitro or p-dimethyl amino phenyl]-3- (1,3,4-thiadiazole-2-yl-5-{3,5-dimethyl phenoxymethylene}) imidazolidine-4-one [6,7]. 2-[ p-nitro or p-dimethyl amino phenyl]-3- (1,3,4-thiadiazole-2-yl-5-{3,5-dimethyl phenoxymethylene}) thiazolidin-4-one [8,9]. The prepared compounds were characterized by spectral methods FT-IR ,1H-NMR and some physical properties with evaluation of their biological activity.
